For those who are still unable to grasp the unlocker method, use this as a full tutorial. [even though one was already posted, I find this much more in depth :D]
[Skip each step you've already done out of 1 and 2.]
1. Download the latest Yoonade update. for below 4.5, place it into the granchase folder, normally C:\Ntreev\Grandchase\... And for newer updates place it somewhere else, preferably your desktop.
2. Download Unlocker from here:
x32 =

x64 =

Make sure to download the correct version for your system. It's common knowledge, but to find your operating system's bit style, click the start button, followed by right-clicking the computer button and selecting properties for windows 7 users, and windows vista. It is shown in the "System Type" section.
I repeat: Download and install the one that fits what your operating system is. If you do not, you'll find Unlocker just simply sits and does nothing when you open it, and you'll have to do a full uninstall before installing the correct one.
3. Start up Yoonade's hack as said. Once at the title screen, the tutorial says to right click C:\Ntreev\Grandchase\Stage\AI\ai.kom and use the unlocker tool by clicking the Unlocker part which also has a wand beside it. Again, if you installed the wrong version, it might not be available so that's a sheer sign.
4. Click unlock all in the window that pops up and you're done, it'll close itself out, simply continue with what the tutorial at the front page says.
I think it might be a good idea to add this to the front to make sure people know exactly what to do in case they fail the normal tut, plus your unlocker link is for x32 only;with those direct links it's easier to find which one you need.
